This invention relates generally to television apparatus and inparticular to a housing and supporting means for the picture means oftelevision receiving apparatus.

In .television receiving apparatus of the prior art it is usual toemploy picture or scanning tubes in providing for a visual display ofthe televised material. These tubes are usually about sixteen totwenty-four incheslong,` with the picture face or screen being arrangedat one end thereof. It is evident, therefore, that the picture face ismost conveniently viewed when the tube is in a substantiallylongitudinal position in its associated cabinet or supporting structure,with the picture face arranged at the cabinet front. However, therelatively long length of the tube-requires a cabinet of considerabledepth to completely enclose the tube in this position whereby `toappreciably increase its size and bulk, as compared to the usual consoleradio cabinet, and hence its cost. In attempts to overcome this increasein cabinet size, the picture tubes have been arranged in a substantiallyvertical position within the cabinetswith the picture face arranged in atop wall or panel of the cabinet. In order to have the representationson the picture screen visible from a position in front of the cabinet, atop lidv or cover for the cabinet is provided having a mirror or likereflecting surface on the 'underside thereof in operative associationwith the picture face. Although this 'arrangement oi the picture tube inthe cabinet appreciably reduced the size of the cabinet, particularly asto depth, it was not entirely satisfactory because of the indirectviewing of the representations on the picture screen, and the limitedview of the reiiecting'mirror .over a rather restricted radius, as wellas longitudinal level, from a position before the cabinet. Also amirrorutilized in this manner reduces the illuminating elect of. the picturescreen, and further increases the cost of the television apparatus.

It is an object of this invention, therefore, to l television apparatusincluding a shallow cabinet for a scanning tube in which the tube issup-r Cil ported to 'provide for the ,projection of the picture screenduring operation of the apparatus from the front of the cabinet and forthe moving of the entire tube within the connes of the cabinet when theapparatus is not in use.

A still further object of this invention is to "provide televisionapparatus including a shallow 'cabinet and a scanning tube which ispivotally supported in the cabinet to provide for an angular swinging ofits picture screenvduring operation in an arc outwardly f rom the `frontof the cabinet, and for a positioning of the tube entirely within thecabinet when the television apparatus is not in use.

A feature of this invention is to provide a cabinet for televisionapparatus including a scanning tube of elongated type, which is shallow,has substantially integrally assembled top and side portions to providefor an overall rigid construction, is relatively inexpensive in cost,and is cooperatively assembled with means for supporting the scanningtube to provide for a substantially longitudinal operating position ofthe tube 'with its picture face at the front of the cabinet and for asubstantially vertical rest position thereof entirely within theconfines of the cabinet.

A further feature of this invention is found in the provision of ashallow cabinet for television apparatus including an elongated typepicture unit, which has a compartment for the unit provided with an openside at the front of the cabinet and means in the compartment forpivotally supporting the picture unit so that'the picture screen thereofis pivotally movable across v such open side in an arc projectedoutwardly from the frontof the cabinet. A cover for ,the opencompartment side is carried by the picture unit meanstherein to provide`for the assembly and removal of the same from the cabinet as a completeunit. Y

' Further objects,.features and advantages Vof this invention willbecome apparent from the iolf lowing description when taken inconnection with the accompanying drawings in which:

Fig. 1 is a front view of a cabinet for television and radio receivingapparatus showing the picture means in an operating position;

Fig. 2 is a side view of the cabinet in Figi 1 showing the picture meansin an operating position corresponding to that in Fig. l, with parts ofthe cabinet being removed for the purpose of clarity; I

Fig. 3 is illustrated similarly to Fig. 2 and shows the picture meanswith a cooperating lens for the picture screen; v

Fig. 4 is a front view of the cabinet showing the idle or rest positionfor the picture means;

Fig. 5 is a fragmentary detail view looking at the picture means fromthe rear as viewed in Fig. 4; A

otally supported at one end on the mounting plate -38 by axis means 38and having an enlarged bearing portion 34 to releasably lock ,the axismember 32 in such bearing. vThe latch member I3 and I4, respectively.Intermediate the abovef mentioned two compartments is a compartment I8for receiving a scanning or picture unit I1 for the televisionapparatus. 'I'he intermediate compartment I8 isseparated from the twoend compartments by abbreviated side wall members evident, therefore,that the top 2i of the .cabinet 38 is yieldably maintained in a latchingposition by a tension'spring 43 connected at one end to a lug 44onthe'mounting plate 38, and at its other end to a lug 48 on the latchmember 38.

The pivotal movement of the latching member 38 to a latching andreleasing position relative to the pivot member 32 is defined by thesliding engagement of a pin element 48 carried by the latch in anarcuate slot 41 formed in the mounting platev 38. It is evident,therefore, that the extent of pivotal movement 'of the latch 38 islimited by the length of the arcuate slot 41.

In the assembly of the picture unit I1 in the cabinet I0 the unit isinserted in the compartment I8 through the open side I8 thereof with thescreen 28 toward the front of the cabinet and with each axis member 32positioned on a corresponding one of the side members I8 of thecompartment I8. The entire unit is then slidably moved toward the rearof the cabinet until lthe axes 32 drop into their corresponding bearingportions 34. As the axes or pins 32 approach the bearing portions 34they engage and move the latch members 38 away from a closing posi- Ition relative to the bearing portions 34, against the tension of thesprings 43. Thus on -dropping vof-the pins 32 into the bearing portions34,- the does'not function .as an ordinary lid or cover.

ybut cooperates with the other-fixed fralnefvporl-l tions of the cabinetto'provide in alla cabinet structure which is rigid andruggedandjoapable of easily and solidly supportingtliereintheicoxnbinedweight of the television and radio receiving apparatus. e

The picture unit I1- in comprises a picture tube 24 (Fig. 2)l having alength greater than the depth of the cabinet III.

the compartment le The tube 24 includes a picture face'or screen 28 atone end thereof, and a base or electrical connecting portion 21 at theIother end adapted for mating electrical engagement with a socket or lthelike (not shown) provided at one end of a supported ina mountingstructure including side members 28 (Flgs. 5, 6 and 1) and a baseportion 3|. Each side member 28 is provided with an axisv member 32which is flxed thereon in ausual manner by means of cooperating cupmembers 33. i

The axes members 32 are rotatably supported,

in combination bearing and latching 38 including an open bearing portion34 which is mounted on the top of a corresponding one of ,the wallmembers I3 for the compartment I8.

Each unit n is integrally formed with a mounting plate 38 positionedagainst a sideA of a wall member I8 and secured thereto as by screws311.

ing portion 34 is bent substantially normal to the mounting plate 38.Each axis orv pivot 32 is releasably retained in a corresponding bearinglatching members 38 are immediately returned to a latching or bearingclosing position by the` springs 43. When the unit I1 is removed fromthe cabinet, the latching members 38 are first' moved away from abearing closing position and the unit I1 then lifted from the bearings34 and slidably moved forwardly of the cabinet on the side walls I8.Itis seen, therefore, that the unit I1 is inserted into the cabinet I8as a unit through the open side I8 of the compartment I8 and isreleasably supportedftherein to facilitate its removal and assembly forservice and manu- .70 As is clearly evident, from Figs. 6 and 7, thebearas previously mentlned, the cablnetln is of.

a relatively shallow construction, and the tube 24 may be about two feetlong, which length is Vappreciably longer than the depth of the usualcabinet now usedV for console radios and contemplated for use withtelevision apparatus. Thus when the picture tube is in a longitudinalposition, as when the television apparatus is in operation, the picturescreen is projectedforwardly from the cabinet (Fig. 2) for directviewing. With the picture screen 28 at the front of the cabinet and alsoprojecting outwardly fro'm the cabinet, the area before the cabinetwithin which the. screen can be easily and comfortably portion 34 bymeans of a latch member 33 piv- 75 viewed is appreciably increased. Alsobrvirtue of the angular swinging of the picture screen vertically acrossthe open side I9 of the compartment, adjustment of the screen islaccomplished to provide for a positioning thereof at a desired heightfor viewing by persons seated before the cabinet. The retention of thescreen 26 in a desired adjustedposition is obtained by means includingcounterweights 41' carried on the mounting structure for the pictureunit at the end thereof opposite the picture screen 26. The weights areof a predetermined size and adapted to cooperate with the frictionalresistance at the bearings 34 to maintain the picture unit I1 stationaryat any set position. It is evident of course that when thefpicture unitis not adjustable, the weights 41 can be eliminated and suitable meansprovided to lock the unit-. in its rest and operating positions.

When the television apparatus is not in operation the unit l1 is`swingable downwardly from its substantially longitudinal position shownin Fig. 2 with a'portion projecting from the cabinet I to asubstantially vertical position shown in Figs. 4.and 5 completely withinthe compartment I6 and entirely within the connes of thecabinet l0.'I'he wall portion 4 8 of the mounting structure for the picture unitl1, which is arranged opposite the base portion 3l and is substantiallycoextensive in length withv the tube 24,h constitutes a cover or lid forthe open side I9 of the compartmenty I6` Thus as the unit Il ispivotally moved to a substantially vertical position, the cover `48 ismoved into a position for closing the side i9' and hence the compartmentI6. As is clearly shown in Fig. 4, the cover 48 in its closing positionforms apart of the front of the cabinet I0. Thus when the 'televisionapparatus is not in operation, the entire picture unit Il is completelyenclosed within the cabinet so as to entirely hide from view theunsightly picture screen 26 without in any way providing for an increasein the depth of the cabinet I0. A large and bulky cabinet is thusentirely eliminated, while permitting the picture tube to operate in alongitudinal position with the picture screen 26 easily andcomfortablyvisible at the front of the cabinet.

In some instances of installation, it is desirable that the picture orrepresentations on the picture screen 26 be enlarged by a cooperatinglens or the like. An assembly of the picture unit Il including a. lens49 arranged in a cooperating relation with a picture tube 24' isillustrated in Fig. 3.` As shown the overall length of the unit I1' issubstantially the same as the overall length of theunit I1 because ofthe tube 24' being somewhat shorter than the tube 24 but having asomewhat wider scanning angle. However, it is ob vious that thetubes 24and 24 may be of the same length andv the unit il' increased to a lengthgreater than theunit Il. 'I'his .increase in the length of the unit l1'is readily accom- .imodated by the compartment I6 by increasing thelength thereof in Aa direction downwardly of the cabinet I0 an amountcorresponding to the increase in the length of the unit I1'. It is seen,therefore, that the housing' and supporting of the picture unit fordirect viewing thereof from the front of the cabinet, and the completeconfinement thereof within the cabinet when it is not in operation, ,isaccomplished equally well with a picture tube alone or with a picturetube in combination witha cooperating lens.

From a consideration of the above description and drawings it is seen,that the inventionproto a plurality o'f operating positions. Theprojecting of the picture screen from the front of the cabinet, when thetelevision apparatus is being operated, improves the visibility of theplcture screen over an increased radius in front of the cabinet whileits complete retraction within the cabinet when it is not being used andthe covering thereof by-a front portion of the cabinet materiallyimproves the overall appearance ofthe cabinet.

Although the invention has been described with reference to a specificembodiment thereof, it is to be understood that it is not to be solimited, since modifications and alterations can be made Atherein whichare within the fullintended scope of the invention as defined by theappended claims.
